GL extruders

Gearless (GL) single screw extruder series with high-torque drive concept

The GL (= gearless) extruder series offer an alternative drive concept. A frequency-controlled, high-torque AC motor is used to drive the screw, with the screw and the motor’s output shaft forming a single line. The high-torque AC motor has a high degree of efficiency at all levels – even under partial load. Since the drives of the GL series operate without gears, all those energy losses caused by a gear transmission system, such as flange loss or heating, are also eliminated.
